MOTAT’s New Car Park

For the past year, MOTAT’s Aviation Hall has been defying the challenges posed by an old landfill site as it constructs its new car park and redevelops its Motions Road location in Western Springs.

For the past year, MOTAT’s Aviation Hall has been defying the challenges posed by an old landfill site as it constructs its new car park and redevelops its Motions Road location in Western Springs. The development also includes a cycleway and pedestrian path that connects Meola Road to Motions Road and the paths through the Te Wai Ōrea, Western Springs Precinct.

The car park is a much-needed development for MOTAT and the Western Springs Precinct community. Visitors to the area have often voiced their frustration at the lack of parking in the area, with visitor research indicating that 1 in 4 visitors to the Auckland Zoo and MOTAT drive away after not finding a car park.

The carpark and the MOTAT Aviation Hall are located on capped landfill which makes it unsuitable for most forms of commercial and residential development. MOTAT’s car park will not only support MOTAT, the Westpoint Performing Arts Centre, Auckland Zoo, TAPAC, and local sports centres, but it will also future-proof the precinct while reducing traffic congestion and making it safer for pedestrians and cyclists to move around the area.

As we approach the end of the construction, we reflect on the challenges that were encountered and the innovative solutions that were implemented to deal with them.

Between 1930 to 1976, local residents used the land for the dumping of household waste and chemicals before the landfill was capped and subsequently leased to MOTAT. Due to decades of dumping, the land MOTAT intended for the car park contained several contaminants of concern (COCs) including heavy metals, asbestos, and polycyclic aromatic hydrocarbons often found in oil and gasoline.

Refuse Modelling Map

Before the project started, MOTAT engaged with and got feedback from its neighbours including the Auckland Zoo, TAPAC, Ngā Puna O Waiōrea Western Springs College, Pasadena Intermediate, Seddon Fields Football Club, Westpoint Performing Arts Centre, and local Iwi.

One of the initial challenges faced by the team was data mapping the depth of the refuse in the covered landfill. While there was pre-existing desktop geotechnical information, this was limited, and the team needed to undertake an updated search to ascertain the depth of the landfill and to identify the pockets of COCs that posed a construction and health and safety hazard.

Unfortunately, the team encountered refuse and other contaminated soil at a shallower depth than shown on the original data map. This meant that the Team had to re-think the approach for the construction of the car park to minimise the risks. Through a flexible design approach, the Team devised a plan that could be adapted to the newly identified refuse-pocket locations and any other pockets that were encountered as construction progressed. This innovative approach meant problems were managed more easily as it was planned to expect these refuse pockets.

Once this pre-construction work was completed our contractors, Auckland Civil, were able to proceed with construction.

The team decided on a surface and pavement design that could accommodate the movement and challenges of an old landfill and could be easily monitored and maintained.

Another challenge of the old landfill site was the release of methane, CO2, and other gases as the rubbish breaks down over time. While these gases are harmless in small quantities they can build up and become trapped under large, paved areas like a car park.

In order to remove this potential risk, subsoil drains were laid under the car park that were in turn connected to gas catch pits with domes and grated lids that vented the gases safely away via gas extraction wells and vents.

Example of an active gas collection system

MOTAT engaged with local Iwi in the early design stages to ensure that Kaitiakitanga was acknowledged and interwoven into the design and construction process to protect the natural environment and in particular the health of the nearby Te Tokoroa, Meola Reef. An innovative stormwater runoff plan was developed to ensure that any potentially contaminated storm water coming from the car park was properly dealt with.

A top-of-the-line pump station was installed to enable the stormwater pipes to be laid close to the surface and thereby avoid the risk of the stormwater being contaminated by the landfill refuse. Without this pump, the stormwater lines would have been 1 - 1.5 metres deeper, which would have increased the risk of contamination.

The stormwater runoff is also treated by an underground filter to remove suspended solids, hydrocarbons, and metals to ensure that the water that eventually flows into the Waitematā Harbour via the tidal portion of Waiōrea, Motions Creek is clean and good enough to drink.

One of the other challenges that was encountered was COVID-19, which extended the construction time and costs but these challenges like the others were handled professionally and with good humour by MOTAT and the construction teams.

It is also worth noting that the car park and walk/cycleway incorporate lighting and cameras to increase the safety and well-being of those using the facility.

MOTAT is proud of the team that has managed this project and we can’t wait to reopen the Aviation Hall and car park to the public on 20 August. A big thanks to those who have contributed in different ways including Auckland Civil, Auckland Council, Tātaki Auckland Unlimited, Waitematā Local Board and, Auckland Transport.

Car park Q&A:

Why has MOTAT decided to invest in a car park?

When visiting the precinct, one in four visitors leave after not being able to find a car park. By building additional parking at MOTAT we hope our visitors will find it easier to find parking, making it easier to plan visits to the Museum.  The car park will also reduce traffic congestion
around the museum and facilitate the installation of cycle and walkways.

These improvements to MOTAT’s parking and access will result in added convenience and peace of mind that visitors are more likely to find safe, quality parking close to MOTAT.











What public consultation was done?

Following the identification of parking and access as key challenges to MOTAT visitors, a study was commissioned to investigate the parking and access issues affecting the precinct and recommendations for improvements.

MOTAT has attempted to engage in a thorough and timely manner with all affected stakeholders. This includes stakeholder consultations in March-April 2019 and again in July 2019.

Pricing research was also conducted via an online population survey supplied to Auckland Zoo and MOTAT members and email databases. This was completed in March 2020.

An onsite hui was held in May 2020.  Representatives from local Iwi attended and subsequently provided written support for the project.





Will there be a charge for parking? Where will the money go?

When the Aviation Hall opens in July - parking will be free of charge.

Western Springs precinct parking (MOTAT, Auckland Zoo & TAPAC) will convert to time restricted parking in Summer 2022 and be monitored by Auckland Transport. The charge for parking will be $2 an hour, capped at a total of $8 per day. Read more about the Western Springs Accessibility Project on the Tātaki Auckland Unlimited website here.

When the car park converts to time restricted parking, the revenue from the parking fees collected will go towards the maintenance of the car park and any surplus will be invested into MOTAT collection care and maintenance. Accessible parking will remain free of charge.

Parking outside of the Auckland Transport time restricted hours (5:00 pm - 9:00 am) will be free of charge.

How will I get from the MOTAT Aviation Hall to MOTAT Great North Road?

The MOTAT trams will resume operating their full loop between MOTAT Great North Road and MOTAT Aviation Hall upon the reopening of the Aviation Hall in late July.

Not visiting MOTAT? The heritage trams are free for all visitors to the Western Springs Precinct. Park at the new MOTAT car park and travel via tram to stops outside TAPAC, Auckland Zoo, Western Springs Park or MOTAT Great North Road.

More information on the trams, including a map of the tram route can be found here.

How do I access the new MOTAT car park?

Access to the MOTAT Aviation Hall will no longer be possible via Meola Road.

Please access the new MOTAT car park and Aviation Hall via Motions Road (see above map).


Will education bookings resume in the Aviation Hall ?

Education and other groups bookings for the Aviation Display Hall are now available to be booked online. To find out what education kete or programme may suit your group, please visit the MOTAT education web page here.

Private events planned through Montana Food and Events are now also available to book. If you are looking to hire the Aviation Hall for a private event or function, please email: katreen@montanafoodandevents.co.nz



Can I park at MOTAT Great North Road?

Limited street parking is available along both Great North Road and Motions Road.

However, to avoid circling the area in search of a car park, we recommend you park and catch the tram from the new MOTAT car park on Motions Road and enjoy the view of Western Springs Park on your journey to MOTAT Great North Road.
